All shrimp are sensitive to water quality. I think that if not overstocked and with regular water changes (with aged water) and a few stem/fast growing plants + moss, they'd be okay. RCS would probably fare better than ghosts.

I'll soon have two free half gallon cubes left! they can apparently be mounted to the wall. and if I can find a lighting solution I think I want to make some very cute little wall decorations with cherry shrimp :D

@ mo, you should totally fit a lamp on top of yours and use it as a lamp stand!
